How’s your backlog right now? In Part 6 of the Construction Accounting Series, Eric sits down again with CPA Kathe Barrington to unpack what backlog really is, and what it isn’t. They dig into why committed-but-unstarted jobs belong on your WIP the day you’re awarded, how to use backlog to forecast labor, equipment, and cash, and why a backlog that looks great in aggregate can still leave you with a nine-month hole in the schedule.
Kathe lays out the ideal backlog-to-revenue ratio, the red flag of growing backlog with compressing gross profit, how client and project-type concentration creates fragility, and who needs to be in the room for the monthly backlog review. If you want backlog to function as a real planning tool, not a vanity number. This conversation is the blueprint.
What you’ll learn:
-
– What backlog actually is – remaining contract, remaining cost, and remaining gross profit to complete
-
– Why letters of intent and verbal awards should NOT count as backlog
-
– Why unstarted-but-committed jobs belong on your WIP the day you’re awarded (and what bank & bonding are looking for)
-
– How to translate a WIP snapshot into a month-by-month forecast of labor, equipment, and cash
-
– How far out you should be forecasting labor (hint: 6–12 months minimum)
-
– The ideal backlog-to-revenue ratio – and why 3–6 months makes Kathe nervous
-
– How backlog profiles differ between GCs and subs, and what that means for planning
-
– The aggregate-number trap: why jobs bunched up at the same finish line signal trouble
-
– When you can tighten margins as you scale – and when compressing gross profit becomes dangerous
-
– Client and project-type concentration risk – diversification as insurance
-
– How often to review backlog (monthly, with the financials) and who belongs in the room
-
– The questions that should drive the conversation beyond the numbers
-
– How to use backlog data when the market shifts – lessons from 2008 and COVID
-
– The three questions Kathe asks first when she takes on a new client’s books

Key Takeaways
- – Backlog is a planning tool, not a trophy. If it’s not driving decisions about labor, cash, and bid strategy, you’re leaving money — and safety margin — on the table.
- – If it’s committed, it belongs on the WIP. Waiting for the first labor hour to post means two months of blind flying.
- – Watch the timing, not just the total. A big backlog with jobs stacked in the same month is a cash-flow cliff in disguise.
- – Growing backlog + compressing gross profit = danger. Scale without margin discipline is how fade and one bad job turn ugly fast.
- – Diversify your basket. Customer and project-type concentration should be monitored monthly, not disclosed after it’s a problem.
- – Review backlog monthly with your project managers, owner, project engineers, and contract-side accounting staff — in the same meeting as the financials.
